Molding dies of hard and brittle materials such as hardened steels or WC were usually ground by resinoid bonded diamond wheel. Recently, cutting process needs to be short and easy by applying diamond cutting. In this study, a new micro milling tool of PCD was developed and basic cutting characteristics were researched in milling of WC. And a feasibility study of a precision fresnel cutting was carried out. From the experimental results, mirror surface and sharp edge were obtained. It is clarified that precision cutting of WC dies can be done with the developed PCD milling tool.
